iOS build: hack to build and install libsqlite3.a

Building the iOS command line utility fails. But frankly, we don't need that,
anyway. I cannot figure out how to tell sqlite that all I want is the library,
so I'm working around that by first building the library, then pretending that
sqlite3 was indeed built in order to be able to run make install. Horrible,
ugly, stupid. But it seems to work.

Also cleaned up the whitespace.
